I'm going to be writing an argument that uses core theory to argue against free will, souls, and for materialism. In the mean time, here are some prerequisite questions to the person who would attempt to deny physics has any ability to give us decisive answers to questions about free will and the existence of souls and who thinks these things exist beyond science.
1. If we have a soul, and that soul gives us free will, wouldn't it have to be the case that this soul has a force that has a causal effect on the physical matter that makes up your body that overrides the existing natural forces known in physics? Yes or no?
2. If yes, that soul-force is either accounted for in the laws of physics or it is not, true or false?
3. If it is accounted for, where in the equations of physics is this found?
4. If it isn't, then where is the evidence of a 5th force overriding the natural forces governing your body? This should have been discovered since this 5th force must be affecting the atoms in your body every second you exercise free will and make a choice.
5. If this force is not part of the existing forces, wouldn't it be injecting new energy into the universe violating the law of the conservation of energy? Yes or no? If no, why not?
